Specification of Letters Patent.

Application filed January 5, 1914. Serial No. 810,395.

To all whom it may concern:

Be it known that I, WALTER RICHARD GROVE, subject of the King of Great Britain, residing at London, England, have invented certain new and useful Improvements in N on-Refillable Bottles, of which the following is a specification.

This invention relates to stoppers for nonrefillable bottles, the object being to provide a stopper which can be readily applied to bottles of usual form and while preventing the refilling of a bottle will also possess means for preventing tampering with the internal parts which avoid such refilling.

The invention comprises the novel combination of parts hereinafter particularly described anl claimed.

In the accompanying drawings: Figure l is a perspective sectional view of one form of stopper according to the invention. Figs. 2 and 3 being respectively a sectional elevation and a plan of the same form of stopper some of the parts being omitted in Fig. 3. Fig. 4 is a plan corresponding to Fig. 2. Figs. 5, 6, and 7 are views of another form of stopper, parts being broken away in Figs. 5 and 7.

In carrying out the invention according to one mode, a stopper is made of earthenware, porcelain or other suitable material in the form of a short cylinder divided by an upright partition so as to form an outlet chamber a, and an inlet chamber 5. The outlet chamber a, is fitted with a flap valve 0 preferably in the form of a small mica or parchment plate secured by a pe or hinged, so as to control a discharge orifice o in the bottom of the chamber a. A ball or other loose weight may be arranged on the flap valve to insure closure. The inlet chamber has a depending part or tube d extending downwardly into the bottle. A communication between this tube and the inlet chamber may be controlled by a small drop valve and the chamber may be fitted with a diaphragm c, of material which is practically impervious to liquid but pervious to air as described in specification No. 985,586. The stopper is closed by a cap 7 having a very small air hole 9, for admitting air to the air chamber Z) and a larger discharge orifice h communicating with the outlet chamber a.

In order to prevent tampering with the valves and the diaphragm, before referred to, by means of a wire or other implement,

the air hole 9 and discharge orifice h are arranged above blocks or abutments j formed in the chambers a and b, and these abutments j may have curved or other faces adapted to guide a wire or other implement away from the valve or diaphragm, should such implement be inserted.

The closing cap for the stopper is preferably providel with downwardly projecting portions is which overlap the above mentioned abutments j to a certain extent and are in close relation thereto so that only sufficient space between the projections and abutments is left to permit of the proper inlet of air and outlet of liquid. By this means, a further safe-guard against insertion of a wire or the like is provided.

A cork washer Z in the form of a ring may be adapted to surround the projecting portion of the cap 7 which enters the outlet compartment a so as to avoid leakage of liquid into the air inlet compartment 6. This lining Z also limits the lift of the valve 0. j

The stopper is mounted on the top of the bottle, and has a spigot 79 provided with a packing ring or washer such as a cork ring or washer o. The stopper is then secured to the bottle by an aluminium or other suitable sleeve 9, the upper or lower edges of which are forced over firmly into contact with the cap of the stopper and with the projecting ridge or heading on the neck of the bottle.

The cap of the stopper is preferably grooved or indented as at s so that the adja cent edge of the sleeve can be forced into it. The stopper is also preferably of slightly less diameter than the diameter of the upper end of the bottle on which it is mounted and the sleeve is shaped accordingly.

The aluminium or other sleeve may be arranged to cover the air inlet so as to necessitate piercing of the cover when the contents of the bottle are to be poured out. A. mark or other indication a being provided to show where the cover is to be pierced.

A. small air inlet hole is preferably arranged in the side or edge of the cap so as to avoid liquid entering it should the bottle not be held correctly during pouring.

It will be understood that the upright partition in the stopper divides the same into two segmental shaped chambers and it is preferred so to arrange the partition that one chamber is larger than the other so that the internal projections on the cap accurately to fit the corresponding chambers so that the cap can only be fitted in one position.

In the form shown in Figs. 5, 6 and 7, the closing cap is made in two separate parts on n the partition in that case extending to the top. The outlet h and air inlet 9 are in the form of bayonet slots as indicated at t in side View, the bottoms j of the slots forming abutments.

I claim:

1. A stopper for non-refillable bottles, comprising a hollow cylindrical part having a partition dividing it into an inlet chamber and an outlet chamber, a discharge valve in the outlet chamber, a tube depending from the inlet chamber, covering means for the top of said chambers having inlet and outlet orifices respectively for said chambers, abutments in said chambers below said orifices, and downwardly projecting portions on said covering means overlapping said abutments and in close relation thereto, substantially as and for the purpose hereinbefore set forth.

2. A stopper for non-refillable bottles, comprising a hollow cylindrical part having a partition dividing it into an inlet chamber and an outlet chamber, a discharge valve in the outlet chamber, a tube depending from the inlet chamber, covering means for the top of said chambers, having inlet and outlet orifices respectively for said chambers, abutments in said chambers below said orifices, and an outer metallic sleeve for securing said stopper on to a bottle, said sleeve having an upper edge adapted to be forced into a groove provided in the afore said covering means, substantially as hereinbefore set forth.

3. 'A stopper for non-refillable bottles,

comprising a hollow cylindrical part having a partition dividing it into an inlet chamber and an outlet chamber, a discharge valve in the inlet chamber, a tube depending from the inlet chamber, covering means for the top of said chambers, having inlet and outlet orifices respectively for said chambers, abutments in said chambersbelow said orifices, and downwardly projecting portions on said covering means overlapping said abutments and in close relation thereto, a spigot on the underside of the stopper and a packing ring on said spigot, substantially as and for the purpose hereinbefore set forth. i

f. A stopper for non-refillable bottles comprising a hollow cylindrical part having a partition dividing it into an inlet chamber and an outlet chamber, a discharge valve in the outlet chamber, a diaphragm in the inlet chamber made of material impervious to water, but pervious to air, a tube depending from the inlet chamber, a cap for the stopper, said cap having a circular groove and inlet and outlet orifices, abutments within the aforesaid chambers beneath said orifices, downwardly projecting portions on the cap overlapping said abutments and in close relation thereto, a spigot for the stopper, packing on said spigot, and an outer metallic sleeve for securing the stopper to a bottle, said sleeve having its upper edge forced into the aforesaid groove in the cap, substantially as hereinbefore set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
